CVE-ID : CVE-2017-5123
Package : linux-zen
Type : privilege escalation
Remote : No
Link : https://security.archlinux.org/AVG-445
The package linux-zen before version 4.13.7-1 is vulnerable to
privilege escalation.
Upgrade to 4.13.7-1.
The problem has been fixed upstream in version 4.13.7.
None.
It was discovered that when the waitid() syscall in Linux kernel v4.13
was refactored, it accidentally stopped checking that the incoming
argument was pointing to userspace. This allowed local attackers to
write directly to kernel memory, which could lead to privilege
escalation.
A local attacker is able to escalate privileges on the affected host.
